I honestly don’t know when this person on Tumblr posted thoughts on Padmé but I thought it had a lot of great points about her character. YMMV of course:
That can be seen as sweet, in a way—that she’s her true, “just Padmé” self with her family. But for me, it’s a little unsettling. She has no home of her own. Padmé’s room is a corner of her family’s estate with depressing political pictures of herself. Her private residence is just another piece of her Amidala persona.
And it’s not that she couldn’t have anything else. She’s a wealthy twenty-four-year-old woman. Rather, it seems like she doesn’t quite know how to exist outside the roles she serves for others—queen, senator, relative, wife. By ROTS, I think it exhausts her. She loves the Republic, she’s devoted to the Republic, but it’s tearing her apart.
